PeriodOis an online resource that will collect and link existing scholarly materials to more clearly define historical, art-historical, and archeological periods. By amassing and cross-referencing this data, Rabinowitz and his co-investigator Ryan Shaw, of the School of Information and Library Science at the Univeristy of North Carolina, hope to provide a tool that will help researchers across disciplines better better reconcile conflicting dates and definitions for period terms used in databases and documents.
